A Secure IoT Architecture for Industry 4.0

This paper proposes a secure and smart IoT architecture for monitoring and automating industrial production processes emulated by flexible manufacturing simulators (FMS) while ensuring data security and privacy. The proposed architecture extends the current FMS architecture with two additional layers. The application layer incorporates an MQTT broker and Domoticz’s dashboard for monitoring and controlling FMS-related data. The cloud layer leverages Google Cloud for secure data archiving and sharing. The solution undergoes a security analysis, demonstrating its dependability, exceptional performance, and robust protection against ARP spoofing and session hijacking.
